Be it knowntlmtllg, Mix Rocns'rnou, director, citizen. ofrit-he Kingdom of Saxony, residing atKle'in-Sedlitz, near Pirnu, Saxony, Germuny,-,-have invented certain new i improvements in Friction-Clutch Presses u n cl tl1eLike, of-which the following is u-specificati'oii; v

In the construction of printing, platen, stumping unddieypresses or other printing niuchinery uctil'utcd by friction clutches, it lizulihiiretofore been usual to mount the lywhcel'loosclycupon the drivingsheft, an arrsngeinent that has the disadvantage that it is difficult to nltcr by hunch the position of themnchinswhent' at rest. Moreover, a powerfiil: brake is required, endxthe adjustment of such a brake when it has become worn byu i ;u1111ot.eusily be accomplished by an in- I iien'ceel printer; En u ppurutus to which thisinvention relates these defects are overcon ehy nrountiug the fly-wheel rigidly upon. thc'shuft ofthe press and providing it with u huh which has the form of friction cone end which in conjunction with u belt-pulley likewise constructed as strict-ion cone, eftects the coupling; a brake which acts upon the fly-Wheel being automatically put in operution when the uncoupling is effected.

The accompanying drawings illustrate two different forms of apparatus in accordance with this invention; wherein Figures 1 and 2 are respectively a front and. a. side elevation of one construction of a side elevation of 3; 5 shows ie elevation at second form of construc tion. i

In the form of the invention shown in Figs. 1 to i there is rigidly keyed to the shaft- 6; the flywheel E). which is furslide;

'otzite fi'eely c-uiloelt pulley (Z providedw l nninnerconi'cel friction sur ingowhich'rests against the ily wheel Z" tends to purute the two friction cones c and (Z. Upon-the hub of the belt pulley (Z there runs the sliding ring 3 which is furnished with tapered projections or tuppets it that are adjacent to the correspondingly oblique faces 2 of the forked upper Pnzn rzno, STAMPING, Ann DIE THE inn.

and thus effects thecoupling. Through the lower end of this rod A: there passes the shell m which is mounted in bearings 12 in the lower part of the fume of the machine and which can be rotated by means oi the disengaging hand lever u rigidly keyed thereon; The lower end of the lever 22 is proi'idcu'withu curveo guide 0 which projects over the l'OlliYV. of the connecting rod in iii-such u inun tardhy means of n spring i when as shown .in l lg'fl'pil-Kf ll no is turned down in the (lllQCllOILOii'ill 2 iro'ni thepositionshown in Fig. 'in; full lines lDt O'tlIG position shown in'dotted 'lihes, thereby braking the fly wheel, said blocks in the latter position binding against the rim of said wheel.

In the modified form of (he inrcutioi'i shown in Fig. 5, the bolt pulley (Z is loosely mounted upon the circiuntercnce oi -the fric icing Vided, the tendency of the springsig/ l'l gageincnt, thereby avoiding the occurrence iotsliding friction between the bell pulley "and the fiy wheel. A halfv ring "u connected 'hy neans of screw bolts 1' that pass through the fly wheel, with the spring support located at the other side of the fly wheel is arrengcd with the unnular'groore 25 in the hub or.

by means of an eccentric connecting link 2 f), cziusc said broke blocits to move sidewise ti'on cone 0 with which the fiywhcc'l is prii;

the belt pulley. The spring support,

inovuble spring support 10. The uncoupling to keep the coupling parts constuntly-in en- 10 can oo moved lengthwise oi the shaft o1 I and-i forced toward the right by means oi llO I of thefly-wheel b friction cones c and c, of

Whieh when the coupling is effected the cone 0 enters into the belt pulley, while during uncoupling the cone 0 enters into the hollow cone (5 which is connected with the ring 3. When the uncoupling lever n is turned down and the connecting rod is correspondingly raised, the friction cones 0 and d will consequently become disengaged while the brake cones 0 and at will be engaged. The springs g in this casealso enable the friction cones to be adjusted, when their friction surfaces have become worn.

The application of the invention is not limited to printing machinery.

Having thus declared the nature of my said invention and in what manner it is to be performed I declare that what I claim 1s l. The combination, with a drive shaft, and fast and loose clutch members mounted thereon, of a shifting ring loosely connected with the loose clutch member and provided with beveled projections; means for normally exerting upon said loose clutch mem ber a tendency toward movement in one direction; an endwise movable rod having a beveled end arranged to engage said projections; and means for advancing said rod, to operate said ring, for moving said loose clutch member in the opposite direction.

2; The combination, with a drive shaft; and fast and loose clutch members mounted thereon, of a shifting member connected one end thereof arranged to en- 3. The combination, with a drive shaft, of

a fly wheel rigidly mounted thereon and having its hub constituting a friction cone; a pulley loosely mounted on said shaft .and constituting a eomple'mental hollow cone adapted to' receiye the first-named cone; a

laterally-momble shifting member loosely carried by the second-named cone; an endwise movable rod having one end thereof arranged to engage the shifting member;

means for normally holding said rod in pro- 50 jected position, with said end in such engage-- ment, to couple the cones;-means for retractmg said rod, todisengage said end; and a spring interposed between said cones for automatically uncoupling the same when 5 said-rod is retracted. p

In testimony whereof I have hereunto set my hand in witnesses.
